RMD hangs while initial loading of the network,

The program hangs during the startup showing 5% progress in "Extracting elevation data and computing networks".

Reason:
RM is trying to load a file on a path or drive that does not exist anymore. This file is stored in either RMW.ini or the registry. Information in RMW.INI can be found at: RMW.ini or Program_Settings.

Solution:

Workaround:
You start the program with a shortcut,  open the properties and just add a fictious name as argument.
